float values are rounded up to int, collectd load plugin unusable

[oryband]

First of all - this plugin is very useful, so good job. It's also cleanly written 👍

It looks like this line converts all values to integer. This is problematic since some values reported by collectd can be floats and/or between 0 and 1.

For example, the collectd load plugin usually reports values very close to 0, and this bug causes all values to be rounded up to 0, showing as if there is no load.
